A woman goes into an antique shop to buy furniture, and notices a large
mirror, which the owner refuses to sell, claiming that it's possessed.
She persuades him to let her borrow it for a few days. When she gets
home and looks at it, she discovers that it has the power to show her
the sexual escapades of all the people throughout history who have
looked into this mirror.

The best of Shaun Costello's comparatively big budget period (HOT
DREAMS being the competition), PANDORA'S MIRROR also stands as the
finest TWILIGHT ZONE type adult film ever made, achieving a sustained
eeriness right from its opening frames through deliberate pacing,
exceptionally beautiful cinematography (credited to "Paolo Coeli") and
Costello's by now exceedingly familiar record collection (Bernard
Herrmann's VERTIGO theme, a couple of Mike Oldfield tunes in addition
to newer selections like Pino Donaggio's music from De Palma's CARRIE
and the traditional "Woman of Ireland" made popular by Stanley
Kubrick's BARRY LYNDON) plundered for soundtrack purposes.

This haunting adult film remains one of the best
to come out of the genre's Golden Age. Costello has taken the utmost
care with every aspect of production.
